The host retains a fallback processing capability for messages that do not fit fast-path criteria, with the device providing assistance such as validation even for slow-path messages, and messages being selected for either fast-path or slow-path processing. A context for a connection is defined that allows the device to move data, free of headers, directly to or from a destination or source in the host. The context can be passed back to the host for message processing by the host. The device contains specialized hardware circuits that are much faster at their specific tasks than a general purpose CPU. A preferred embodiment includes a trio of pipelined processors devoted to transmit, receive and utility processing, providing full duplex communication for four Fast Ethernet nodes. |

Hardware task manager
A hardware task manager for an adaptive computing system. The task manager indicates when input and output buffer resources are sufficient to allow a task to execute. The task can require an arbitrary number of input values from tasks. Likewise, output buffers must also be available before the task can start to execute and store results. The hardware task manager maintains a counter associated with each buffer. For input buffers, a negative value for the counter means that there is no data in the buffer and the buffer is not ready and the associated task cannot run. Predetermined numbers of bytes, or “units,” are stored into the input buffer and an associated counter is incremented. When the counter value transitions from a negative value to a zero the high-order bit of the counter is cleared indicating the input buffer has sufficient data and is available to be processed. |

Utilization of Reed-Solomon coding in mobile/hand-held digital television receivers
Receivers for recovering ancillary data from parallel concatenated convolutional coding. (PCCC) imbedded in digital television (DTV) signals can utilize the non-systematic (207, 187) Reed-Solomon (RS) codewords included in the DTV signals to facilitate DTV receivers already in the field to continue being able to receive main-service transmissions. Such a receiver attempts to decode each non-systematic (207, 187) RS codeword in a time slot selected for reception. If such RS decoding is successful, indication of such success is used to verify the correctness of bits of the ancillary data or correct them when turbo decoding the PCCC encoding ancillary data in the time slot selected for reception. The updating of ancillary data bits during cycles of turbo decoding updates the non-systematic (207, 187) RS codewords in the time slot selected for reception, increasing the likelihood of RS decoding of those RS codewords being successful during subsequent cycles of turbo decoding. If all the non-systematic (207, 187) RS codewords in the time slot selected for reception are successfully decoded before reaching a prescribed maximum number of cycles of turbo decoding, turbo decoding can be discontinued early to conserve operating power. |

When those messages are received at the second node, the message is injected back into the power line on the other side of a gap in power line coverage. This method of transmission backup will continue until power line connectivity is restore upon which the preferred method will be selected and used. |

Crossbar switch system
Each chip arranged in each crossbar switch creates and issues, if a packet is input, a log collection packet for collecting a log of the packet. Each chip collects a log related to a transfer of the input packet. Each chip embeds, in the issued log collection packet or a log collection packet transferred from a crossbar switch in a previous stage, the collected log. If a transfer destination of the packet is other than the crossbar switches, each chip stores, in a storage space, the log embedded in the log collection packet and then transfers, to the transfer destination, only an original packet in which the log is deleted. In contrast, if the transfer destination is a crossbar switch, each chip transfers the log collection packet to a crossbar switch in a next stage. |

Hybrid packet-switched and circuit-switched telephony system
A hybrid telephony system with packet switching as well as circuit switching optimizes utilization of transport networks, and is accessible from any conventional telephone set. A call originating from a circuit-switched network is passed through a gateway computer to a backbone packet-switched network, and then through a second gateway computer to a second circuit-switched network where it terminates. The voice of both the originating party and the terminating party is converted to data packets by the near-end gateway computer and then converted back to voice by the far-end gateway computer. In an alternative scenario, the originating party uses a computer on the packet-switched network, which replaces the originating circuit-switched network and the originating computer. Powered by CPUs, DSPs, ASICs disks, telephony interfaces, and packet network interfaces, the gateway computers may have media conversion modules, speech processing modules and routing resolution modules, and are capable of translating telephony call signaling as well as voice between circuit-switched and packet-switched networks. Optionally, the gateway computers may also have analog trunking modules, MF and DTMF digit modules and special services modules, in order to support analog circuit-switched networks and secure telephone calls. |

Facilitating non-SIP users calling SIP users
A technique for allowing a non-SIP user to call a SIP user includes dialing an established service number that indicates a desire to place a call to a SIP user. The SIP URI of the intended call recipient is included in a call setup protocol message associated with dialing the service number. A non-SIP network recognizes the call to the service number and the SIP URI from the UUI parameter of the call setup message. The call is then routed to a gateway for interfacing between the non-SIP network and the appropriate SIP network where the SIP URI is extracted from the message received by the gateway and used to generate an SIP INVITE message for establishing the call with the intended SIP user. |
